java.sql.SQLException：參數索引9超出范圍（1，8）

Question

我有一個要求，我必須使用三個IN參數和6個OUT參數調用MySql存儲過程。

程序

DELIMITER $$ 
DROP PROCEDURE IF EXISTS GET_PRODUCT_INFO $$

CREATE PROCEDURE GET_PRODUCT_INFO(IN productName varchar(25),
  IN divisionID int(11), IN productQuantity int(11),
  OUT Price double, OUT price_without_vat double,
  OUT vat double, OUT Quantity int, OUT ProductsId int, OUT ExpDate date)

BEGIN

   select I.quantity into Quantity from ProductInventory I
     where I.pname=productName and I.divid=divisionID ;

   if Quantity > productQuantity THEN
      select P.productID,P.price,P.price_without_vat,P.vat, I.quantity,P.ExpiryDate 
        into ProductsId,Price,price_without_vat,vat,Quantity,ExpDate 
        from product P,ProductInventory I
        where P.pname=productName and I.pname=productName 
          and P.orgid=divisionID and I.divid=divisionID ;

      update productinventory 
        set quantity=(quantity-productQuantity)
        where pname=productName and divID=divisionID;
   END IF;
END $$

call GET_PRODUCT_INFO('Crocin',1,2,@Price,@price_without_vat,@vat,@Quantity,@ProductsId,@ExpiryDate)$$

在這里，我能夠在mysql cmd提示符下檢索記錄...但是，每當我嘗試從JDBC代碼調用該過程時，都會收到此錯誤

例外

java.sql.SQLException：參數索引9超出com.mysql.jdbc.CallableStatement.checkParameterIndexBounds（CallableStatement.java:1002）的com.mysql.jdbc.CallableStatement.checkIsOutputParam（CallableStatement.java）的范圍（1，8） ：971）

callableStatement = (CallableStatement)con.prepareCall("{call GET_PRODUCT_INFO(?,?,?,?,?,?,?,?,?)}");
callableStatement.setInt(2, 1);
callableStatement.setInt(3, quantity);
callableStatement.registerOutParameter(4, Types.DOUBLE);
callableStatement.registerOutParameter(5, Types.DOUBLE);
callableStatement.registerOutParameter(6, Types.DOUBLE);
callableStatement.registerOutParameter(7, Types.INTEGER);
callableStatement.registerOutParameter(8, Types.INTEGER);
callableStatement.registerOutParameter(9, Types.DATE);--->Exception here

Answer 1

callableStatement.setString(1, "SomeText");

也包括這個。 您錯過了1參數。
